Helmets are mandatory. It is recommended each rider bring (2) water bottles, a tube, patch kit, tire levers, pump, a spare tire and warm clothing in layers that can be shed as the day warms up and carried with you. Do not leave clothing at SAG stops. NOTE: No personal support vehicles please. Headphones, Walkmans and iPods are forbidden by law. Please DO NOT urinate in public! Use the Port-A-Potties we provide at the rest stops.
